Abstract
A core pulling mechanism of a die wheel connection hole of a plastic trash can comprises an upper compound plate and a lower compound plate of a die. The upper compound plate is connected with a static die plate, a cavity insert is installed below the static die plate, a movable die plate is installed on the lower compound plate, a cavity insert is installed on the movable die plate, a die cavity is formed between the cavity insert and the cavity insert, a molded trash can is arranged on the die cavity, and a pair of wheel connection holes are manufactured at the bottom of a can body of the trash can. The core pulling mechanism is characterized in that a core pulling oil cylinder is installed on the outer wall of two sides of each cavity insert respectively, a piston rod of each core pulling oil cylinder is connected with a connection hole core which penetrates through the cavity inserts to be matched with the connection hole. The technical scheme is that the core pulling oil cylinder drives the connection hole core to conduct core pulling from the wheel connection hole, so that the core pulling mechanism is simple in structure, stable and reliable in oil cylinder driving work and smooth in core pulling.
Description
Technical field
The utility model relates to plastic garbage bin mold wheel connecting hole core-pulling mechanism, belongs to the mould of plastics field.
Background technology
Adopt mould of plastics to produce plastic garbage bin, dustbin is divided into indoor dustbin and outdoor dustbin, and outdoor dustbin generally all is placed on the both sides of street or road, and near the people supplying throw away puts rubbish.Therefore the volume of outdoor dustbin is how bigger, and when still expiring rubbish in the dustbin, the weight of dustbin is very heavy, carries gruellingly, so a common barrel end at dustbin installs wheel additional, makes the dustbin conveniently moving.Wheel is the bucket end that is installed in dustbin through axis hole, therefore, must be shaped on connecting hole in an end at the bucket of dustbin, so after the dustbin injection mo(u)lding, need earlier could whole dustbin to be taken out outside the mould the demoulding of loosing core of wheel connecting hole.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, provides a kind of employing oil cylinder to drive fuse and looses core, and simple in structure, action is stable, reliable, the plastic garbage bin mold wheel connecting hole core-pulling mechanism smoothly of loosing core.
The technical scheme of the utility model plastic garbage bin mold wheel connecting hole core-pulling mechanism is: comprise compound plate and following compound plate on the mould, last compound plate connects solid plate, mount type cavity insert under the solid plate down; On the following compound plate moving platen is installed; Core is installed on the moving platen is inserted, core insert and cavity block between constitute die cavity, the dustbin of moulding is arranged in the die cavity; The staving bottom of dustbin is shaped on the one wheel pairs connecting hole; It is characterized in that described cavity block both sides outer wall installs the oil cylinder of loosing core separately, the piston rod of the oil cylinder of respectively loosing core connects the connecting hole fuse, and the connecting hole fuse passes cavity block and matches with connecting hole.
The plastic garbage bin mold wheel connecting hole core-pulling mechanism of the utility model, described cavity block both sides outer wall is installed the oil cylinder of loosing core separately, and the piston rod of the oil cylinder of respectively loosing core connects the connecting hole fuse, and the connecting hole fuse passes cavity block and matches with connecting hole.After the dustbin injection mo(u)lding, mould not die sinking is earlier extracted out from the wheel connecting hole but the oil cylinder of loosing core at first drives the connecting hole fuse that is connected on the piston rod; Drive the moving platen die sinking by injection machine power then; Core is inserted and cavity block is separated, dustbin is stayed core and is inserted to go up and insert mobilely with core, from cavity block, deviates from; At last with dustbin from the core taking-up of inserting, the demoulding is accomplished.This programme drives the connecting hole fuse through the oil cylinder of loosing core and from the connecting hole of wheel, looses core, and is simple in structure, and it is stable, reliable that oil cylinder drives action, looses core smoothly.
Description of drawings
Fig. 1 is the utility model plastic garbage bin mold wheel connecting hole core-pulling mechanism structural representation.
The specific embodiment
The utility model relates to a kind of plastic garbage bin mold wheel connecting hole core-pulling mechanism, and is as shown in Figure 1, comprises compound plate 1 and following compound plate 2 on the mould; Last compound plate connects solid plate 3 down, and mount type cavity insert 4 under the solid plate is installed moving platen 5 on the following compound plate 2; Core is installed on the moving platen is inserted 6, core insert 6 and cavity block 4 between constitute die cavity, the dustbin 7 of moulding is arranged in the die cavity; The staving bottom of dustbin 7 is shaped on one wheel pairs connecting hole 71; It is characterized in that described cavity block 4 both sides outer walls install the oil cylinder 8 of loosing core separately, the piston rod 9 of the oil cylinder 8 of respectively loosing core connects connecting hole fuses 10, and connecting hole fuse 10 passes cavity block 4 and matches with connecting hole 71.The present technique scheme is installed the oil cylinder 8 of loosing core separately at described cavity block 4 both sides outer walls, and the piston rod 9 of the oil cylinder 8 of respectively loosing core connects connecting hole fuse 10, and connecting hole fuse 10 passes cavity block 4 and matches with connecting hole 71.After the dustbin injection mo(u)lding, mould not die sinking is earlier extracted out from wheel connecting hole 71 but the oil cylinder 8 of loosing core at first drives the connecting hole fuse 10 that is connected on the piston rod 9; Drive moving platen 5 die sinkings by injection machine power then; Core is inserted 6 opened in 4 minutes with cavity block, dustbin 7 is stayed core and is inserted on 6 to insert with core and 6 move, and from cavity block 4, deviates from; At last dustbin 7 is inserted from core and 6 taken out, the demoulding is accomplished.This programme drives the connecting hole fuse through the oil cylinder of loosing core and from the connecting hole of wheel, looses core, and is simple in structure, and it is stable, reliable that oil cylinder drives action, looses core smoothly.
